Anyone know of any? Would like to try out some as I saw a pair of custom mades on tower that had great sound and the guy said he only had 50w to each(x4) Sound was very clear out to 100' behind his boat as they went by. He said they were clear as a bell when riding. I have 4 6.5" Memphis spks. in AudioFormz cans powered w 50w ea and not as clear as I would like when outside of wake even though we have angled the outer cans. Don't really need lows from tower spks so the horns really made sense, and man they were LOUD. Ideas please, Tks
